WebJun 25, 2024 · The gray area is the planar silicon-blazed grating with grating constant of 4 μm. To increase reflectivity, a 100 nm-thick aluminum (Al) film is added to cover the grating surface. Since the grating is fabricated by anisotropic wet etching process, the grating groove is formed by intersecting (111) faces and the apex angle of the grating is ... WebKnowing the energy of the emitted photoelectrons and the frequency of the incident light, you can calculate a value for Planck's constant h. ... Place the reflection grating on an optics platform about 12m away and arrange so that it can see the lamp through the crack in the door. The reflected spectrum returns across the front of the hall to ... the walking dead lounge pants
